Review a dated duty scenario
Pick a mapped 10-digit code and enter origin, value, and entry date. The calculator determines which Chapter 99 measures apply to that scenario; it does not force this provision into the result.
Plain-English explanation
HTS 9903.45.25 is a Chapter 99 tariff modification under Safeguard. For a qualifying entry during this provision's effective period, the published rate notation is 30%; the source instructions determine how that notation relates to the underlying base duty. Country scope is not on file in Tandom's catalog. Suspended; the duty engine does not apply it while the suspension flag remains in effect. Tandom maps 4 base HTS codes to this provision for catalog screening; a dated calculator scenario determines whether it applies.
Historical or scheduled rate mechanics
This catalog record does not establish an additive rate relationship, so the page preserves the published notation without adding it to the base rate. Suspended; the duty engine does not apply it while the suspension flag remains in effect. The calculator checks the selected entry date and shipment facts before including any Chapter 99 provision.
Description
Authoritative scope text from the U.S. Harmonized Tariff Schedule
Modules as defined in note 18(g) to this subchapter, when the product or originating good of a country other than a country described in note 18(b) to this subchapter, except as provided in heading 9903.45.27 or heading 9903.45.29
How to use this provision
Filing mechanics during the provision's effective period
Chapter 99 provision 9903.45.25 is a tariff modification — it doesn't classify a product on its own. When a base 10-digit HTS code falls within this provision's scope during its effective period and a shipment matches the country and date conditions, the broker declares the base code at entry and follows the source instructions for reporting 9903.45.25 on a separate line.
Worked example
Published notation shown without assuming an additive rate
For an illustrative $10,000.00 entry during a period when this provision is in effect, assume an importer files 8541.42.00.10 (crystalline silicon photovoltaic cells of a kind described in statistical note 12 to this chapter) from a country in the published scope and all product conditions are met. The published rate notation is 30% and the base HTSUS rate is Free. The catalog does not carry a structured additive relationship for this provision, so this example does not add the displayed percentage to the base rate. Suspended; the duty engine does not apply it while the suspension flag remains in effect.
No numeric total is shown because a published percentage alone does not establish whether the provision is additive, total, or otherwise conditional. Use the calculator for a dated scenario.
